not so much a word as an action. when
someone is talking to you and you dont really want to hear what they have to
say or you
just dont feel like listening you just go pssssss... and eventually they will get the point and shut up.
hillary: hey for once in your
life could you pick up your
damn clothes around here.
Me:psssssssss...(while she is talking)
Hillary: why are you making that hissing noise, stop making that hissing noise, what
ever i'm leaving!
Me: saved again by the psss...
